I DONT REALLY LIKE ANY OF THE MODELS.  THE ETA SEEMED TO HAVE THE
BEST PLACEMENT OF THE 18Z LOW...BUT IT GIVES CLE .37 INCHES BY 18Z.
WHILE THE NGM SEEMS TO MOVE THE LOW TOO FAR EAST TOO QUICKLY
CONSIDERING NO REAL JET MOVE IT.  BY 18Z TOMORROW ETA HAS LOW IN NW PA
WHILE THE NGM HAS THE LOW HALF A STATE TO THE EAST IN NE PA.  FCST
BASED ON ETA AND MOVEMENT OF LOW OVER PAST 6 HOURS. NW PA HAS BEST
CHANCE OF PRECIP AS DENNIS DRIFTS NORTH BEFORE FINALLY BEING KICKED
OUT BY FRONT NOW IN NW OH.  SCATTERED SHOWERS STARTING TO DEVELOP
AHEAD OF FRONT JUST ENTERING NW OH.  FRONT SHOULD BE PAST TOL BY 00Z
SO REMOVED POPS THERE FOR EVENING.  WITH THE FRONT AND LINGERING
MOISTURE FROM DENNIS KEPT SCATTERED SHOWERS IN CENTRAL AND NE OH FOR
TONIGHT.
